Richard Calaba commented on KYLIN-1844: --------------------------------------- How can we switch-off dictionary for high cardinality dimensions ??? > High cardinality dimensions in memory > ------------------------------------- > > Key: KYLIN-1844 > URL: https://issues.apache.org/jira/browse/KYLIN-1844 > Project: Kylin > Issue Type: Improvement > Components: Query Engine > Affects Versions: v1.2, v1.5.2 > Reporter: Abhilash L L > Assignee: liyang > > A whole dimension is kept in memory. > We should have a way to keep only certain number / size of total rows to be > kept in memory. A LRU cache for rows in the dimension will help keep memory > in check. > Why not store all the dimensions data in hbase in a different table with a > prefix of dimensionid, and all calls to the dimensions (get based on dim > key), is mapped to hbase. > This does mean it will cost more time on a miss. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
